Be it known that 1, Lnivis T.- lllincox, a citizen of the United States, residing at Peekskill, in the county ot YVestchester, State otNeiv York, have. invented an Improvenient in LiquidfFuel Stoves, ot which the following is a specification.

My invention relates to oil burners of the kind usually employed in oil cooking and other stoves.

1n burners of this kind, it is common practice to provide a horizontal oil supply pipe communicating with a suitable reservoir, and to mount the burners on this pipe and supply them with oil by tapping the pipe at each burner. ln this arrangement the burners are supported on the oil supply pipe which in turn is supported in the frame o1 the stove, and thevconnection between the supply pipe and the burner is made in various Ways for the purpose of supporting or bracing the Wick trough, which in turn supports the otherl parts of the burner.v

ls/.lany ditliculties have been encountered,

in using this construction, and many dediiiiculties.. One otl thepi oblems which presents .itself is that of making a simple, strong and effective connection between the oil-supply pipe andthe pipecommunicating between it and the burner trough, which Will resist and maintain its position under strains of all -kinds and which may be `quickly and easily made and adjusted Without the use of soldering or similar operations. It is to provide an efficient device of this character that the present improvements are yprimarily de- '.signed.

The improvements Vare illustrated in the accompanying drawings referred to herein, and in which Figure 1 is a vertical longitudinal section of a supply pipe, burner trough and connection taken medially there-v of, with the elevation. Y

plan respectively of' a vmodiiied form of conncction.

Figs. S and 9 are details of modiiied forms of the parts shown in Fig. 4, the former showing the said part in elevation and the latter the pipe with a conical seat therein.` and Fig. 10 is an elevation of the connection showing the same with a threaded end.

A simple and effective arrangement of burner and supply7 pipe is that shown in Fig. 1, in which a burner member, or Wick shell or holder 10, sometimes called the burner trough, is placed on the horizontal oil supply pipe 11 in such a manner that the said pipe extends diametrically across its bottom, and the connecting member 12 is securedL to the Wick holder on the outside thereotl and to the supply pipe immediately below it. -In view ot the tact that this is the only support of the Wick holder, combustion tubes mounted thereon and other parts it is important that the connection shall be very strong and secure and capable of holding the parts in proper position under all the ordinary conditions and strains of use. The items oit' simplicity and economy are also important ones, and the simplification ot' such parts as are used is therefore desirable. The present improvements meet these requirements.

ln carrying out the present improvements the supply pipe 11 is indented or countersunk as shown at 13, and provided with a small fiat table 14, and then tapped at the bottom of the indentation as shown at 15 to receive the angular end 16 of the connection'12, secured to the Wick holder 10 b means ot the integral liange plate 17 by having rivets 18 or other suitable fastenings passed through openings 19 in the plate and through the outer Wall of the holder. Communication betweenv the wick holder and the supply pipe is established through the channel 20. The connection 12 has a shoulder 21T, and betweenthis shoulder and the pipe a gasket 22 of. compressible material is located. In making the parts the pipe is lirst grooved or indented.A This may be done by readyl for use.

Fig. 9, so that the metal surrounding it will if'orm an inwardly tapering seat, or it may be threaded as shown in Fig.' 10. In the iirst case the end of the connection 12 Will be conicalas shown at 24, and in the second case it will be threaded as shown at 25.

TheVr parts described are noiv placed in position, and the splitloop 26 passed around the bottom of the pipe and closed over the horizontal portion jot the connection 12. The loop is preferably made of spring metal so that it can be spread open to permit this. This construction obviates the necessity of placing the loop on the pipe before the parts are assembled, and causes it to assume its proper position. rlhe ends ot the loop 26 overlap as indicated at 2T and 28 and are provided with tapped openings 29 adapted to receive a bolt 3() which is turned down therein until it bears against the top ot' the connection 12 immediately above the sea-t ot the said connection. Further turning or' the bolt causes its lower end to press against the said part and thus torce the extremity 1G of the connection 12 into the opening oi the pipe 1l, and also compress the gasket22. rIhe device'is now completed and In the modification of Fie. l() the strap may be dispensedwvith, and the threaded end 25 screwed down into the threaded opening et the supply pipe by rotai-ting the connection and thewick holder after these .parts have been connected. In addition to the rivetingot the plate 17 to the Wick holder the connection 12 is secured thereto by having the lip extended under the bottom of said holder and united therewith.

In the modification ot Figs. 6 and 7 the double loop 32 isused, andthe Wick holder suspended from the pipe connection at the side of the supply pipe, and as in the pre- 'erred form, it is held against movement in all directionsby the socket joint'above described. v

In this construction however, the bolt preferably passes freely through an opening provided therefor in the top of the loop and engages withv a nut in which it turns so as to tree the nut Yagainst the under surtace or' the top of the' loop when the endot the nut is turned int-0 contact with the connecting member to secure the parts in place. 1

I claim as my invention:`

1. vIn au apparatus of the class described, a 'supplyY pipe, a burnervmember, a 'fitting secured at one end tothe said burner and adapted at its other'e'nd to directly engage an opening providedzthereitor in the said supply pipe, and a clamp engaging the said fitting and supply pipe to make a tight joint bet-Ween the same.

2. In an' apparatus ofthe class described,

bear against the said flattened tace thereof,

and a clamp engaging the said `fitting and supply pipe to makeA a tightV Joint between the same.
